Nick Kyrgios recovered from a set down to reach the U.S. Men's Clay Court Championship quarter-finals. The Australian fired 22 aces and saved both break points he faced in the match to improve his winning record this season to 78.57%. Despite concerns regarding Nick's physical condition, the No.4 seed seemed fully recovered from the right elbow injury that forced him to withdraw from four consecutive tournaments - Rotterdam, Delray Beach, Acapulco and Indian Wells.

Ivo Karlovic continues to impress in Houston. The 39-year-old advanced to his second quarter-final of the season with a 7 - 5 7 - 5 win over qualifier Denis Kudla. Known as one of the best servers in tennis history, the 2007 champion dropped just six points behind his first serve in the previous round. On the other hand, Karlovic won 40.70% of the points played on Kudla's serve and broke the American three times.

These two players will face each other for the 5th time in their careers with Kyrgios winning all their previous four official encounters on the ATP World Tour.

The bookmakers are well aware of Nick's dominance over this opponent with the Australian as the big favourite at 39/100 at 5Dimes while William Hill offers 21/10 for Karlovic's victory. Even though we agree with Kyrgios favouritism, it won't be easy for the world No.24 to break Ivo's serve. With this in mind, our suggestion is for you to add the Over 25.5 at 81/100 at the green listed bookmaker Pinnacle to your betting picks as the most valuable play for this contest.
